Abstract
A knee airbag installed in a lower portion of an instrument panel has a deployed condition wherein it extends rearward and upward. The airbag has a left lobe, a right lobe, and a central portion between and joined to the left and right lobes. A vent is formed in the reaction surface of each of the lobes to allow inflation gasses to escape from the airbag when, during a crash event, an occupant force applied forwardly against the lobes is below a threshold level. When the occupant force reaches or exceeds the threshold level, the vents are urged against the instrument panel to substantially block the escape of inflation gasses. The threshold level is selected such that a child-sized occupant standing forward of a desired passenger seating position exerts less than the threshold level.

The specific embodiment
As required, at this specific embodiment of the present invention is disclosed; It should be understood, however, that disclosed embodiment only is example of the present invention, the present invention can implement with form various and that substitute.Accompanying drawing may not be drawn in proportion; Some features may be exaggerated or be minimized, to show the details of specific components.Therefore, the details on concrete structure disclosed herein and the function should not be interpreted as restriction, and only is interpreted as using in every way representative basis of the present invention for instruction those skilled in the art.
Fig. 1 shows the passenger accommodation of automotive vehicle 10 with schematic form, show passenger's (that is, non-driver) side of dress circle.Seat 12 is arranged in the rear of gauge panel or instrument carrier panel (IP) 14 with conventionally known structure.Occupant 16 is shown in seat 12, is in normal sitting position.Seat 12 limits the seat of expectation, and when occupant 16 correctly was sitting in the seat 12, occupant 16 was called as the occupant in the tram.
Upper body air bag module 18 is arranged among the IP 14, be arranged on the IP 14 or otherwise integrated with IP 14, and upper body air bag module 18 is positioned at the top of IP, so that safety air bag can be towards the occupant 16 who takes one's seat upwards and/or backward inflation.Upper body air bag module 18 is shown schematically as and comprises chest safety air bag 20, as the occupant restraint field known, chest safety air bag 20 with fold, wind up or otherwise compacted condition deposit.Charging blower 22 is shown as and is positioned at IP 14, and is very near apart from upper body air bag module 18, and is connected with safety air bag by appendix 24.Alternatively, charging blower can be oriented to be close to upper body air bag module 18, and charge air conditioning more directly can be discharged in the safety air bag 20.
Chest safety air bag 20 and knee airbag 30 can be made by the pore-free material of flexibility (such as, nylon).
As the vehicle safety field known; chest safety air bag 20 and knee airbag 30 are parts of occupant restraint system, and occupant restraint system comprises bound control module (RCM) (not shown) and one or more crash sensor and/or occupant sensor (not shown).Depend on that the performance of occupant restraint system and program design are together with the deceleration that triggers air-bag deployment or the character (order of severity, direction, time length etc.) of collision; can order chest safety air bag 20 and knee airbag 30 to launch simultaneously or successively expansion, the expansion of chest safety air bag 20 and knee airbag 30 is intended to realize the occupant safety of the best opportunity.
When occupant 16 correctly fastens one's safety belt (" in the tram ") in seat 12 except when be grown up, chest safety air bag 20 is in the partial inflation state and knee airbag 30 is in fully outside (or approaching fully) inflated condition, and Fig. 2 shows the interior structure of vehicle of Fig. 1.Chest safety air bag 20 is formed and otherwise is suitable for inflating backward towards occupant 16, with the upper torso area of contact and occupant restraint.As well known in the art, chest safety air bag 20 can comprise interior panelling, tether, lignilite and/or be used for realizing the aerating position of expectation and the feature of inflation sequence.
As in Fig. 3 A as seen, knee airbag 30 comprise left protuberance 34, right protuberance 36 and be arranged on left protuberance and right protuberance between and connect the central portion 38 of left protuberance and right protuberance.When knee airbag 30 launches (inflation), be called as action face 42 towards the surperficial of IP 14 and with the surface of this Surface Contact of IP 14, be called as first type surface 43 towards occupant 16 surface.When airbag inflated, action face 42 is close to the described surface of IP 14.Central portion 38 comparable protuberances 34,36 thin, thus the middle section between protuberance 34,36 forms recess 40.
As well known in the art, realize by interior panelling, tether, lignilite and/or other features the expectation inflated shapes of knee airbag 30 and position.Left protuberance 34 and right protuberance 36 can be along horizontal spaced distance D, and distance D is determined by the expection spacing (consistent with normal adult knee spacing) between left knee 16a and the right knee 16b when the occupant 16 of tram is in suitable seat.Preferably, chosen distance D is so that the occupant of the body sizes of maximum range provides maximum protection to having as far as possible.
Vent 44,46 is formed in protuberance 34,36 the action face 42.Action face 42 tightly can be with respect to peripheral part of action face recessed or rise and fall round vent 44,46 zone (can be called as the vent supporting part), thereby when acting on the Surface Contact of surperficial remainder and IP 14, the surface of vent and IP 14 separates slightly.The vent supporting part of action face 42 this recessed or rise and fall allow vent 44,46 not with the Surface Contact of IP, thereby make vent 44,46 keep not being blocked, unless and until knee airbag 30 compresses forward IP consumingly by the quite a large amount of pressure forward that is applied to protuberance by the occupant.The surface of IP 14 also can comprise recessed (not shown), this recessed position that will align with vent 44,46 when knee airbag 30 launches that is positioned at.But the vent supporting part of the fluctuating on recessed substituted role surface 42 like this is provided, and is perhaps provided in addition except the vent supporting part of the fluctuating of action face 42, is not blocked to guarantee vent 44,46.
The power deficiency that compresses forward safety air bag that applies is so that vent 44,46 compresses the situation that IP 14 closes vent consumingly thereby Fig. 3 A shows that occupant's knee 16a, 16b contact with safety air bag 30.This situation can appear when occupant 16 is subjected to safety strap 32 correct constraint in seat 12.In this case, the charge air conditioning that enters protuberance is relatively freely overflowed by vent 44,46, and safety air bag 30 can forced aeration.
The power that knee 16a, the 16b that Fig. 3 B shows the occupant compresses the level of IP 14 consumingly with the vent supporting part that is enough to make action face 42 compresses forward protuberance 34,36 so that vent 44,46 situations about fully being stopped by contacting with IP.When vent 44,46 was blocked by this way, charge air conditioning was overflowed hardly, thereby pressure gathers fast knee airbag 30 is interior, to provide stable buffering to occupant 16.
By making vent compress consumingly the threshold level that level that IP 14 closed or substantially closed the required forward direction occupant power of vent is called as occupant's power.Contacted with protuberance 34,36 if thereby occupant 16 throws away forward the knee 16a, the 16b that force the occupant with respect to seat, then may surpass the threshold level of occupant's power.This can occur in the serious collision of vehicle or between other quick deceleration periods and/or when the occupant in seat 12 not securely/when correctly fastening one's safety belt.Knee 16a, 16b are (for example if the occupant correctly fastens one's safety belt, because the front/rear adjustment of seat 12 and/or occupant's femur are long) be positioned at position forward like this so that when knee airbag 30 launches, the power of safety air bag contact occupant's knee 16a, 16b is enough to make vent 44,46 to compress consumingly the surface of IP 14, then also may surpass the threshold level of occupant's power.
Referring now to Fig. 4, show the interior structure of vehicle identical with Fig. 1, but during the commitment of airbag inflated event, forwardly have out of position occupant (OOPO) 50 in the seat zone.OOPO 50 is shown as little stature individuality and/or children are individual.For example, some passenger protection test protocols that are used for the automotive vehicle security industry use the test model that represents three years old children's average-size and six years old children's average-size.Test configuration as commonly used shows the place ahead that OOPO 50 stands in seat 12, and the surface of close IP 14.
As shown in Figure 5, OOPO 50 main phases contact with central portion for protuberance 34,36.Therefore, thus being applied to protuberance 34, occupant's power of 36 by OOPO 50 does not reach be used to making vent 44,46 compress consumingly IP 14 and closes vent 44,46 required threshold levels.Because vent 44,46 stays open, so knee airbag 30 or not can be filled, or be filled gradually comparatively speaking, thereby expand backward with the speed to OOPO 50 application of forces hardly.
The recess 40 that is positioned at the middle section of knee airbag 30 can have such size, even this size is so that OOPO 50 departs from the central authorities between the protuberance 34,36 slightly when inflation sequence begins, the inflation of protuberance between IP 14 and OOPO 50 also will be tended to promote OOPO towards position more placed in the middle.If OOPO 50 departs from the central authorities between the protuberance 34,36 slightly when inflation sequence begins, then the ventilation by the protuberance that is not blocked reduces to inflate the power that produces.
Although described exemplary embodiment in the above, these embodiment are intended to describe all possible forms of the invention.On the contrary, the word that uses in specification sheets is descriptive words and non-limiting word, it should be understood that can carry out various changes in the situation that do not break away from the spirit and scope of the present invention.In addition, the feature of each embodiment of realization can be combined, to form further embodiment of the present invention.
